Product Description:
The RKL4560 cable is a flexible motor supply lead manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. Designed for moving-axis installations such as gantry robots and handling modules, the product carries drive output to the motor while providing auxiliary conductors for encoder or brake circuits. By grouping power and control cores inside a single robust sheath, the cable simplifies wiring runs in automated cells and preserves signal integrity during continuous flexing.
Electrically, the cable supports a phase-to-ground rating of 600 V AC; this matches the output range of standard Rexroth servo inverters. Four copper power conductors with a cross-section of 10.0 mm² each are arranged symmetrically, giving adequate ampacity and keeping voltage drop low over long runs. A dedicated green/yellow core takes the count to 4 load paths. The outer diameter measures 22.2 mm, yet the polyurethane jacket keeps weight and abrasion low. When laid in static trays the sheath may be bent down to 5xD without exceeding insulation strain. Its jacket material is PUR, and conductor resistance is limited to 1.91 Ω/km at 20 °C, supporting efficient current flow.
Dynamic performance is critical in cable chains; the RKL4560 endures 5 million flex cycles without conductor breakage when minimum motion parameters are observed. For moving applications the permissible bend drops to 7.5xD, ensuring shield integrity while still allowing compact loops. The insulation remains flexible from -20 °C up to +40 °C, so cold starts and heated enclosures do not compromise bending life. Two control pairs, specified as 2 × 1.0 mm² plus 2 × 1.5 mm², share the same PUR jacket, and the material’s cut-through resistance helps the cable maintain mechanical stability under constant acceleration.
